Embodiment 1

[0030] It is implemented in Hualuping Village, Buga Township, Zhaoyang District, Zhaotong City, Yunnan Province. The geographical location is 103.73° east longitude, 27.24° north latitude, and 1994.7m above sea level. The implementation site is convenient for drainage and irrigation, the terrain is flat, and the fertility of the implementation field is medium; before it was used as green manure, the soil type was medium loam. The variety tested was Yunyan 87.

[0031] 1. Harvesting tobacco leaves

[0032] Before capping the tobacco plants, remove 2 bottom leaves, leave 20 leaves per plant, and count from bottom to top to cap the leaves. Select 100 representative tobacco plants and divide them into upper, middle and lower parts to determine the leaf positions. The roasted leaf position is the 10th-12th leaf, and the roasted leaf position of the upper leaf is the 15th-17th leaf.

[0033] The lower leaves of the normal tobacco leaves in the field are underripe (4 days in advan...

Embodiment 2

[0039] Except that the position of the roasted leaves and the harvesting period of the tobacco leaves are different, the others are the same as in Example 1.

[0040] Harvesting of tobacco leaves: the middle leaves of normal tobacco leaves in the field are suitable for harvesting (on the day of normal picking and roasting).

Embodiment 3

[0042] Except that the position of the roasted leaves and the harvesting period of the tobacco leaves are different, the others are the same as in Example 1.

[0043] Harvesting of tobacco leaves: Harvest the upper leaves of normal tobacco leaves in the field that are overripe (the normal picking and roasting date is delayed by 6 days).

[0044] With reference to the harvesting time of different degrees of maturity of tobacco leaves (see Table 1), comparative examples were also set (comparative examples were the same as in Example 1 except that the position of the roasted leaves or the harvesting period of the tobacco leaves were different), as shown in Table 2.

Abstract

The invention relates to a high-temperature slow-yellowing picking and curing matched technology for tobacco in an intensive automated curing barn and belongs to the technical field of production of flue-cured tobacco. High-temperature slow-yellowing curing conditions for the intensive automated curing barn are provided, and the best harvesting periods, matched with the high-temperature slow-yellowing curing conditions, for the upper, middle and lower parts of the tobacco are provided, namely the undercuring harvesting period for the lower part, the proper curing harvesting period for the middle part, and the overcuring harvesting period for the upper part. The technology is simple in operation and can effectively solve the problem that the quality of related tobacco is poor when a same curing process is adopted for curing the upper, middle and lower parts of the tobacco; the quality and coordination of the tobacco after curing are improved to the maximum degree, and meanwhile the quality and flavor of the tobacco can also be improved through the high-temperature slow-yellowing curing technology.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco production, and relates to a matching process for picking and roasting tobacco leaves in an intensive automatic curing barn that slowly turns yellow at high temperature, and specifically relates to the limitation of the harvesting period of tobacco leaves and the limitation of the parameters of the tobacco leaf baking process in an intensive automated barn. Background technique [0002] During the whole production process of flue-cured tobacco, great changes have taken place in the appearance and interior of tobacco leaves through baking. With the gradual increase of temperature, the macromolecular substances in it are gradually transformed into aroma-causing substances, and with the loss of moisture, they can be fixed and save. As a key part of flue-cured tobacco production, curing directly determines the final performance of tobacco leaf quality. For most tobacco areas in my country, ...
